The Detroit Lions rookie defensive end suffered an ankle injury two weeks ago against the Cowboys. Despite getting the bye week to rest, Ansah has missed both practices this week.

He was seen wearing a walking boot on his left leg in the locker room Tuesday, a possible sign he's dealing with the dreaded high ankle sprain, and missed Wednesday's workout.

With end Jason Jones already out for the season, rookie Devin Taylor likely would start on the right side of the line if Ansah isn't available for Sunday's first-place battle against the Chicago Bears.

Detroit also signed an end, Austen Lane, this week. That's another possible indicator that the Lions expect to be without Ansah for the near term.

Ansah hasn't missed a game this year, although he missed a chunk of training camp and two preseason games with a concussion.
